Export scenes as .obj

[FedeClaudi]

Hi,

Thank you for the amazing resource.

I've been trying to export actors and whole scenes as .OBJ files, but I think I've found a bug.

In vtkplotter.vtkio both .write() and .save() should support .obj files:

def write(objct, fileoutput, binary=True):
    """
    Write 3D object to file. (same as `save()`).
    Possile extensions are:
        - vtk, vti, npy, ply, obj, stl, byu, vtp, vti, mhd, xyz, tif, png, bmp.
    """

but an error is thrown if one tries to save as .obj:

 Unknown format scene.obj file not saved.

In write() in the if/else statements checking for the file format there is no if ".obj" in fr
so ".obj" is not recognized as a valid format.

Is ".obj" going to be supported in the future?

Hi Federico,
thanks a lot! the bug is actually in the documentation... I hadn't added the wavefront OBJ format because VTK will only support it in future releases (though the class is already present in the nightly builds).. so it will be for sure available.
Meanwhile I've added it in vtkplotter so that it will there when available from vtk.
Thanks for drawing my attention to it,
Cheers
Marco
